Description

Apparatus for Dispensing Liquid

Field of Invention

The present invention relates to an apparatus used for cleaning. More particularly, the present invention relates to a dispenser for dispensing liquids onto a surface.

Background of Invention

Cleansing solutions such as liquid soap are basic cleaning aids which are used when bathing. Prior to the introduction of liquid soaps, solid bar soaps have been the most popular means used to aid in removal of dirt and other impurities from skin during bathing.

Bar soaps are disadvantageous as they are slippery when wet, and if not gripped properly, may slip out of hands and drop onto floor, becoming unhygienic as a result. Additionally, an improperly stored bar soap may leave an unpleasant residue and dry out. Since liquids such as liquid soaps are stored in a container prior to being poured out for use, they do not suffer such disadvantages.

While many people may prefer liquid soaps over bar soaps, some people may still prefer having the feeling of a solid object rubbed against their skin to improve the cleaning action which cannot be achieved using liquid soap alone. To this end, bathing accessories such as brushes, sponges and loofahs are used in conjunction with the liquid soaps to improve the bathing experience.

In view of the above, it is advantageous to provide a means to enable use of a liquid while providing an enhanced tactile feeling.

Summary of Invention The present invention relates to an apparatus for dispensing liquid, comprising a body defining a reservoir for holding liquid, a second valve in fluid communication with the reservoir to allow liquid to be dispensed from the reservoir when pressure is applied onto the body, a refill port in fluid communication with the reservoir to allow liquid to be introduced into the reservoir and a plurality of scrubbing elements for scrubbing and cleaning one or more surfaces.

The term “liquids” used throughout the specification shall be taken to refer to any fluids that are used to aid in cleaning a surface or body and may contain stearates, salts, fragrances, surfactants, humectants, exfoliants and other compounds known to a person having ordinary skill in the art.

Figures 1-7 show an apparatus (10) for dispensing liquid, the apparatus (10) being a preferred embodiment of the present invention.

Referring now to Figure 1 , a top perspective illustration of the apparatus (10) may be seen. The apparatus (10) is intended to function as a cleaning accessory that enables use of liquid cleansing solution in lieu of a traditional cleansing solution bar while providing a tactile feel for a user who may prefer a bathing accessory having a textured surface for cleaning.

The apparatus (10) comprises a squeezable, resilient and hollow body (11) that is fabricated from any elastomeric material such as silicone. To improve durability, the body (11) is moulded as a single piece instead of separate pieces which are then fused together. Alternatively, the body (11) is made from more than one piece which are then fused together. The body (11) is made using a compression mould or other similar processes so as to ensure structural integrity of the body (11) during multiple/prolonged times of squeezing action. This also ensures uniform compression and decompression of the body (11). Preferably, the body (11) has a substantially teardrop shape that provides improved ergonomic comfort when holding and squeezing, enabling the apparatus (10) to be hand- holdable.

A plurality of scrubbing elements such as raised studs (18) are preferably disposed at top portion of the body (11) to improve gripability of the body (11) and to also provide a cleaning/scrubbing effect when the plurality of studs (18) is rubbed against a surface. The plurality of studs (18) may be in the shape of rounded, cylindrical or conical protrusions or any other conceivable shapes. Preferably, the plurality of studs (18) is integrally formed with the body (11) and are formed when the body (11) is moulded. Referring now to Figure 2, a bottom perspective illustration of the apparatus (10) may be seen. A plurality of scrubbing elements such as bristle clusters (19) are preferably disposed at bottom side of the body (11). The plurality of bristle clusters (19) provides a cleaning/scrubbing effect when bristle clusters (19) are rubbed against a surface. In the nonlimiting example shown in Figure 2, each bristle clusters (19) may vary in number of bristles, bristle size, bristle height and diameter from one bristle cluster to another bristle cluster. As with the plurality of studs (18), the plurality of bristle clusters (19) is integrally formed with the body (11).

A valve cap (15) is provided and is fastenable over a valve (shown as 14 in Figure 4) to prevent liquids from being inadvertently squeezed out from the body (11) when not in use. Preferably, the valve cap (15) includes male threads which correspond with female threads provided on the body (11) to enable fastening of the valve cap (15) over the valve (14). The valve cap (15) also includes a raised protrusion (15a) that enables manipulation by fingers to twist the valve cap (15) open or close. In the non-limiting example shown in Figure 2, the protrusion is X-shaped. The protrusion (15a) also assists in opening and closing of a refill valve port cap (17a) which will be explained in greater detail in a later part of this description.

Referring now to Figure 3, a side perspective illustration of the apparatus (10) may be seen. A plurality of side grooves (20) disposed on left and right sides of the body (11) are provided to improve gripability and also provide a scrubbing effect when the plurality of side grooves (20) is rubbed against a surface. The side grooves (20) may be in perpendicular, angular, concentric circular order, wave-like pattern or a combination thereof. The plurality of bristles (19), the plurality of studs (18) and the plurality of side grooves (20) in combination provide a varied tactile sensation for a user when using the apparatus.

Referring now to Figure 4, a side cross-sectional illustration of the apparatus (10) may be seen. As can be seen from this figure, the body (11) defines a reservoir (12) which holds liquid. The liquid may be squeezed out of the body (11) through a second valve (14) which is in fluid communication with the reservoir (12). The volume of the reservoir (12) is between 50 - 200 ml. It is envisioned that the volume of reservoir (12) is larger if intended for applications that require a higher volume of liquid such as washing cars. The second valve (14) is secured to the body (11). The second valve (14) preferably includes resilient members that open and allow liquid to exit when the liquid dispenser (10) is squeezed and close and prevent liquid from exiting when no pressure is applied onto the liquid dispenser (10). Preferably, the second valve (14) component is obtainable from valve manufacturing companies. It is recognized that the body (11), once squeezed, may take a while to return to its original shape due to the second valve (14) partially restricting entry of air into the reservoir (12). Optionally, a first valve (13) such as an umbrella valve in fluid communication with the reservoir may be provided to assist the body (11) in returning to its original shape after being squeezed. The first valve (13) is secured to the body (11).

The first valve (13) allows one-way entry of air through an aperture (13a) into the reservoir

(12) while preventing liquid in the reservoir (12) from exiting. Thus, when the body (11) is squeezed, liquid exits the reservoir (12) via the second valve (14) but not via the first valve

(13) and when the body (11) is released, air will enter the reservoir (12) via the first valve (13) to help enable a smooth and quick return of the compressed body (11) to its original shape.

A refill port (16) is provided to allow liquid to be refilled into the reservoir (12). The refill port (16) is capped with a refill port cap (17) that is configured in a similar manner as the valve cap (15). The refill port (16) is secured to the body (11).

In the non-limiting example shown in Figure 2, the refill port cap (17) includes an X-shaped depression (17a) that corresponds with the X-shaped protrusion (15a). The X-shaped protrusion (15a) may be placed into the X-shaped depression (17a) and twisted in a counterclockwise direction to unfasten the refill port cap (17) and twisted in a clockwise direction to fasten the refill port cap (17). Conceivably, the protrusion (15a) and depression (17a) need not be limited to an X-shape as illustrated in Figure 2 and may take on any shape that allows torque to be transmitted from the protrusion (15a) to the depression (17a).

Referring now to Figure 5, a front perspective illustration of the apparatus (10) may be seen. Preferably, a loop (21) is provided at narrow end of the body (11) to enable a lanyard, cord, or the like to be passed through so that the liquid dispenser (10) may be hung when not in use. As with the plurality of studs (18), the loop (21) is integrally formed with the body (11).

Where it may not be apparent, adding a lanyard to the loop (21) allows the apparatus (10) to be slung from a user’s forearm via the lanyard during cleaning and reduces likelihood of the apparatus (10) being dropped. If not in use, the apparatus (10) may be hung at a desired location such as a shower faucet.

Referring now to Figure 6, a rear perspective illustration of the apparatus (10) may be seen. Instead of passing a lanyard through the loop (21), a receptacle (24) may be formed at larger end of the body (11) to enable a lanyard (illustrated as 22 in Figure 7) to be removably attached to the body (11).

Referring further to Figure 7, a lanyard (22) which is connected to an end (25) which includes a joint (not illustrated) which allows the end (25) to be releasably connected to the receptacle (24) via the ball joint. The joint is securable with the receptacle (24) by connections means such as screw connection. The lanyard (22) may also include a loop (23) that is able to hold the valve cap (15) while the apparatus (10) is used which reduces likelihood of misplacing the valve cap (15).

Apparatus (10) for bathing animals, washing articles such as crockery, vehicles may not have scrubbing elements as described and can be replaced or covered with textile fabrics and/or different scrubbing materials which provide a suitable scrubbing effect. The apparatus (10) may be adapted onto an external component that comprises a larger body to provide a larger surface contact area whereby the apparatus (10) dispenses liquid while the external component scrubs and cleans a contacted surface. Optionally, the apparatus (10) has a handle for easy manoeuvring and/or extension arm for reaching a distanced surface.

The invention being thus described, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the embodiments as disclosed therein. Such modifications are to be considered as included in the following claims unless the claims by their language expressly state otherwise.
